Answer:
Jessica has $13,80 and Sarah has $58.20.
Step-by-step explanation:
Let j be the amount of money that Jessica has.
Let s be the amount of money that Sarah has.
s + j = 72
Since Sarah has 3 more than 4 times what Jessica has...
s = 4j + 3
So 4j + 3 + j = 72
5j = 69
j = 13.8
So Jessica has $13,80.
Therefore Sarah has $58.20.

Answer:
x = 58°
Step-by-step explanation:
ABCD is a cyclic quadrilateral and opposite angles are supplementary , so
∠ DAB = 180° - 121° = 59°
The angle between a tangent and a chord is equal to the angle in the alternate segment, then
∠ ABD = 63° , thus
x = 180° - (59 + 63)° = 180° - 122° = 58°

Answer:
B
Step-by-step explanation:
(5, -1) and (-5, 2)
y=-3/10x+1/2
-1= 3/10 (5) + 1/2
-1 = -15/10 + 1/2
-1 = -1.5 + 0.5
-1 =-1
